* sys: remove socketpair for AF_INET and AF_INET6Michael Tüxen2018-12-0471-1061/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * OpebBSD: remove socketpair() for AF_INET and AF_INET6. socketpair() is only supported on AF_UNIX. * NetBSD: remove socketpair() for AF_INET and AF_INET6. socketpair() is only supported for AF_UNIX. * FreeBSD: remove socketpair() for AF_INET and AF_INET6. socketpair() only supports AF_UNIX. * Linux: remove socketpair for AF_INET and AF_INET6. socketpair only supports AF_UNIX. * Autogenerated files. These are manually generated for all platforms you are not running on. FreeBSD in this case. * executor: rebase. * sys/freebsd: rebase. * sys/linux: use AF_UNIX based socketpair for nbd. This was suggested by Dmitry. Fixes #845

* sys/linux: limit init_module size argumentDmitry Vyukov2018-10-301-0/+7
| | | | | | | Kernel tries to vmalloc whatever we pass as size and it's not accounted against memcg. As the result it can lead to massive OOM kills of everything running on the machine. Strictly saying, the same applies to finit_module with a sparse file too, but there is no simple way to handle that.

* sys/linux: fix up descriptionsDmitry Vyukov2018-10-3012-59/+60
| | | | | | | 1. Extract consts on the latest linux tree. 2. Don't manually define O_TMPFILE/O_ACCMODE/_LINUX_CAPABILITY_VERSION_N, they are defined in kernel headers. 3. Don't use CLOCK_SGI_CYCLE as clock id, it's not implemented.

* sys/linux: slightly refine perf descriptionsDmitry Vyukov2018-10-2811-22/+75
| | | | | CPU argument can be -1. It makes sense to mmap perf fd.
* sys/syz-extract: support missing arch headersDmitry Vyukov2018-10-2817-49/+795
| | | | | | | | The latest Linux kernel misses some arch-specific headers on some archs: asm/a.out.h asm/prctl.h asm/mce.h Support that.
* sys/linux: floppy interface descriptionDenis Efremov2018-10-289-5/+1368
| | | | | | | | | | For floppy fuzzing you need to enable: 1) CONFIG_BLK_DEV_FD in your kernel configuration 2) "cmdline": " -fda FLOPPY.img " in syzkaller configuration Signed-off-by: Denis Efremov <efremov@linux.com> Signed-off-by: Alexander Popov <alex.popov@linux.com>
* sys: check that target consts are definedDmitry Vyukov2018-10-191-20/+30
| | | | | | | | | | | | | | Currently when we get target consts with target.ConstMap["name"] during target initialization, we just get 0 for missing consts. This is error-prone as we can mis-type a const, or a const may be undefined only on some archs (as we have common unix code shared between several OSes). Check that all the consts are actually defined. The check detects several violations, to fix them: 1. move mremap to linux as it's only defined on linux 2. move S_IFMT to openbsd, as it's only defined and used on openbsd 3. define missing MAP_ANONYMOUS for freebsd and netbsd 4. fix extract for netbsd
* sys/linux: prohibit FAN_OPEN_PERM and FAN_ACCESS_PERMDmitry Vyukov2018-10-159-23/+196
| | | | | | | FAN_OPEN_PERM and FAN_ACCESS_PERM require the program to reply to open requests. If that does not happen, the program will hang in an unkillable state forever. See the following bug for details: https://groups.google.com/d/msg/syzkaller-bugs/pD-vbqJu6U0/kGH30p3lBgAJ

* sys/linux: prohibit EXT4_IOC_SHUTDOWNDmitry Vyukov2018-09-1313-69/+25
| | | | EXT4_IOC_SHUTDOWN EXT4_IOC_SHUTDOWN on root fs effectively brings the machine down in weird ways.

* prog: add concept of "special pointers"Dmitry Vyukov2018-08-302-19/+31
| | | | | | | | | | | | | | | | | Currently we only generate either valid user-space pointers or NULL. Extend NULL to a set of special pointers that we will use in programs. All targets now contain 3 special values: - NULL - 0xfffffffffffffff (invalid kernel pointer) - 0x999999999999999 (non-canonical address) Each target can add additional special pointers on top of this. Also generate NULL/special pointers for non-opt ptr's. This restriction was always too restrictive. We may want to generate them with very low probability, but we do want to generate them. Also change pointers to NULL/special during mutation (but still not in the opposite direction).
